Hi James, we did sucessfully run two TE410P with 8xE1 in a decent Intel P4-3200 machine with quite heavy line usage. No codec conversion course.
I don't believe that there is a hard limit of E1s coded into Asterisk. But the maximum lines you can squeeze out of your specific hardware depends on so many factors (asterisk version, hardware etc).
